If the \fBGNUTLS_E_REHANDSHAKE\fP +error code is not seen, then the handshake request was +not followed by the peer (the TLS protocol does not require +the client to do, and such compliance should be handled +by the application protocol). + +Once the \fBGNUTLS_E_REHANDSHAKE\fP error code is seen, the +calling application should proceed to calling +\fBgnutls_handshake()\fP to negotiate the new +parameters. + +If the client does not wish to renegotiate parameters he +may reply with an alert message, and in that case the return code seen +by subsequent \fBgnutls_record_recv()\fP will be +\fBGNUTLS_E_WARNING_ALERT_RECEIVED\fP with the specific alert being +\fBGNUTLS_A_NO_RENEGOTIATION\fP. A client may also choose to ignore +this request. + +Under TLS 1.3 this function is equivalent to \fBgnutls_session_key_update()\fP +with the \fBGNUTLS_KU_PEER\fP flag. In that case subsequent calls to +\fBgnutls_record_recv()\fP will not return \fBGNUTLS_E_REHANDSHAKE\fP, and +calls to \fBgnutls_handshake()\fP in server side are a no\-op. + +This function always fails with \fBGNUTLS_E_INVALID_REQUEST\fP when +called in client side. +.SH "RETURNS" +\fBGNUTLS_E_SUCCESS\fP on success, otherwise a negative error code. +.SH "REPORTING BUGS" +Report bugs to <bugs@gnutls.org>. +.br +Home page: https://www.gnutls.org + +.SH COPYRIGHT +Copyright \(co 2001- Free Software Foundation, Inc., and others. +.br +Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved. +.SH "SEE ALSO" +The full documentation for +.B gnutls +is maintained as a Texinfo manual. +If the /usr/share/doc/gnutls/ +directory does not contain the HTML form visit +.B +.IP https://www.gnutls.org/manual/ +.PP |
